  1. You could try running a script on each pi, which would detect disconnects and run some commands to try reconnect when disconnected. Google "raspberry pi script ifup wlan0" to see what others are doing. --
  2. In your command raspivid -t XXX What value is XXX? Is it large enough? I think XXX is in millisecond, so XXX=1000 would mean 1 second That might explain why raspivid shows up in top and disappears soon after. --
  3. A couple of things to try 1. That the LAN ip is correct. Try ping instead of ssh, look in your router attached devices and see if the pi is still at 192.168.192.100. 2. Add a display/kbd to it, login and run ifconfig 3. Download a new raspbian on another sd card, use it to boot and see if the pi hardware is working. It could be that your sd card is toast.
  4. When it hangs .. can you do a % sudo ifdown wlan0 % sudo ifup wlan0 Does it come back up? Are there any messages? --
  5. If the wifi dongle needs a USB hub, one possibility is that the pi is underpowered. Check the Amps on the power adapter output, and get a higher amperage adapter. --
  6. Might help if you mention how you knew that the ethernet was not working? You might need some setup. On a terminal window type ifconfig and sudo cat /etc/network/interfaces and reply with the outputs --
  7. Or look for routers which can run open source firmware like ddwrt or tomato. A lot of those would support VPN and would be cheaper than a pi and accessories.
  8. When you VPN from the machines on your local network, do all the machines get different IP addresses? If they do ( use to find out), and say the ip is a.b.c.d try ssh a.b.c.d If the VPN does port forwarding ( might not for free VPNs) this might work. --
  9. A VNC client would work while under VPN. Unfortunately unlike the windows machine you want a vnc "server" to work correctly on the Pi. I havent done this myself, but you can Google "openvpn LAN bypass" to search. Let us know what you find. --
  10. Is that a vnc server running on the windows machine which you can access from another machine on the local network? Do you use a local IP address to connect? A vnc client on the windows machine would work...
  11. Im curious, does this work on your other machines? ssh and vnc remotely while you are on vpn? http://www.raspberrypi.org/forums/viewtopic.php?f=36&t=20402 might explain why this does not work. --
  12. Reviving an old thread, but looks like there are Uninterrupted Power Supplies for the pi now. http://www.piups.net/ --

    Ahhhh, were you trying a HDMI-VGA cable at first? Those don't work very well. HDMI-HDMI works, HDMI-DVI works because both the ends are digital. HDMI-VGA is digitial to analog. Although, the aren't many LCD monitors which do not have at least a DVI input. --
  14. I am assuming you want to copy files from the sd card to the hard drive or vice versa. The easiest way is to do it using the GUI "File Manager" which should be on your desktop. Doubled click on it and it will open a window. Double click on your hard drive icon and it will open another window. You can now drag files and folders from one to the other to copy The command line command for copying is "cp". Do a "man cp" to get the help manual page for "cp". --
